      Phenomenal team to work with. From Sales to Engineering, Customer Service and at the highest level of leadership, the DualBoot partner team is simply great. They are consistent and interested in your success. Once their engineering team has learned your stack, you can't tell from inside to external resources. Work just gets done. I recommend them w/o reservations; start-up or well established firm, you are in great hands with the DualBoot team!

      We have been working with Dualboot for close to a year and the process is perfect. The team is responsive, knowledgeable and talented. The Dualboot team has taken the idea of software and allowed it to be simplified for non-tech minded people. I would recommend them to anyone.
